Nov 16, 2010 (A Wilson) - The occurrence lies within the Eastern Domain of the Goudreau Lake Deformation Zone. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, subparallel to the stratigraphy and the regional foliation. In the immediate Goudreau-Lochalsh area, the GLDZ is coincident with a major contact between Cycle 2 and Cycle 3 volcanics. There is a strong structural control of the gold-bearing quartz veins systems within each of the 070-075° striking high-strain zones within the deformation zone. The Eastern Domain of the GLDZ is 9 km long and 2 km wide and contains narrow brittle and brittle-ductile high-strain zones displaying dextral, oblique slip displacement. Mineral lineations at the Cline Lake area have a consistent shallow plunge to the east and become moderately to steeply plunging in the Godin Lake area. Within the eastern domain, high-strain zones (as well as laminated, quartz-tourmaline and/or quartz-Fe-carbonate veins, fractures and felsic porphyry dikes) are dominantly parallel or at low angles to the east-striking regional foliation. The eastern domain is truncated on the west by the NW-trending Maskinonge Lake Fault.

Dec 07, 2005 (A Wilson) - The occurrence is described as consisting of quartz-carbonate stringers within a strain zone located at the contact between a quartz-feldspar porphyry dike and sheared mafic metavolcanic rocks.

Nov 16, 2010 (A Wilson) - The best assay obtained by Erie Canadian in 1938 was 0.80 dwt from a grab sample collected from a sheared greenstone. The best assay obtained from diamond drilling by Vega in 1980 (DDH 80-13) returned 0.04 oz//t Au over 1.5 feet in siliceous metavolcanics. A 5 foot section of core from Vega DDH 80-16 returned 0.02 oz/t Au, 0.08 oz/t Ag, 0.1% Cu and 0.25% Co. Gold mineralization is associated with pyrite-pyrrhotite-chalcopyrite bearing quartz veins of unknown strike length. Gold values are erratic from these veins.
